Shielding Effectiveness Measurements Using an Apertured TEM Cell in a Reverberation Chamber

Abstract

II TEST CONFIGURATION M e a s u r e m e n t s of n e a r f i e l d s h i e l d i n g effectiveness are performed in a reverberation chamber using an apertured transverse electromagnetic cell as the receiver. This configuration allows one to investigate the electricand magnetic-field shielding properties of a material simultaneously. Coupling to the cell is modeled using small-aperture theory, and predicted results agree well with measured data.
